Heathrow Warns Middle East War Boosts Transfers as Airport Fills

warned on Wednesday that the is pushing more transfer passengers through its terminal network while leaving the West London hub full. , Heathrow's chief financial officer, said: "Heathrow is full" as the airport reported 18.9 million passengers in the first quarter.

The airport said closures of airspace linked to the war in Iran had lifted transfer demand and that it had "temporarily absorbed demand from elsewhere". Heathrow added that passenger numbers for the rest of the year are likely to be affected while there is significant uncertainty in the Middle East.

Heathrow's first-quarter passenger total was up 3.7% year-on-year, while revenue rose 2.3% to £844 million. Ding said the operating limit means "fewer choices and higher fares for passengers and missed opportunities for the UK economy," a line that points to the practical squeeze passengers already face at an airport running close to capacity.

Heathrow said its current operating capacity is one reason it wants to expand. The airport's plan would raise capacity to 150 million passengers a year from 84 million and increase annual flights to 756,000 from 480,000, with part of the M25 moved into a tunnel to make room for the scheme.

The expansion debate remains political as well as operational. Transport Secretary rejected the cheaper £25 billion rival bid from last autumn, while the government review of its is now expected this summer.

Heathrow's own plan is a £50 billion proposal that has been contested for years. The airport said on Wednesday: "Our plan is privately financed, rigorously assessed and focused on value. With the right regulatory framework and government policy in place, we are ready to invest, grow and keep the UK connected to the world," and Ding added: "Expansion is about delivering more routes, more competition and ultimately better outcomes for the people and businesses who rely on us."

For passengers, the immediate picture is tighter choice at a crowded hub, with more transfer traffic feeding through Heathrow as Middle East airspace closures continue to reshape travel patterns. For ministers, the summer policy review now sits alongside the airport's warning that capacity limits are already shaping fares, routes and the broader economics of flying through London.
